It has been a while since I’ve had a chance to play with Ruby, and with 1.9.1 coming out in January I figured I’d go ahead and install 1.9 to get a feel.

Since speed was always an issue in 1.8 I figured I’d re-run my fib.rb script to find the fibonacci number for 35. I ran it against ruby 1.8.7 (2008-08-11 patchlevel 72) and 1.9.0 (2008-06-20 revision 17482), the standard versions for Ubuntu Intrepid Ibex.
